This is a NASA/ESA Hubble Space Telescope picture a comet-like object called P/2010 A2, which was first discovered by the LINEAR (Lincoln Near-Earth Asteroid Research program) sky survey on 6 January. The object appears so unusual in ground-based telescopic images that discretionary time on Hubble was used to take a close-up look. This picture, from the 29 January observation, shows a bizarre X-pattern of filamentary structures near the point-like nucleus of the object and trailing streamers of dust.
